"With the latest releases of Opera, Google Chrome and Firefox continuing to push the boundaries of the web, the once-dominant Internet Explorer is looking less and less relevant every day. But we should expect Microsoft to go on the offensive at its upcoming MIX 2010 developer conference in Las Vegas, where, it has been speculated, the company will demonstrate the first beta builds of Internet Explorer 9 and possibly offer a preview release of the browser to developers. Several clues point to the possibility that the next version of IE will include broad support for HTML5 elements, vector graphics and emerging CSS standards. If Microsoft plays its cards right in Vegas, IE 9 could be the release that helps IE get its groove back in the web browser game."

I find those complaints rather weak. Silverlight using Trident on Windows and Webkit on OSX seems like an advantage for OSX if anything. Only having the COM interface on Windows is a bit more damning, but it is hardly the core use-case for Silverlight, and it is not immediately clear if a COM-like model would fit very well on OSX anyway.
